Abstract: A display device includes a backlight, a display element, a plate for holding at least a portion of an emission surface, from which an image light is emitted, provided on the display element, and a heat dissipation portion that dissipates heat generated from the display element. The display element is connected to the heat dissipation portion via the plate.

Abstract: According to one embodiment, a semiconductor integrated circuit includes a semiconductor integrated circuit a voltage regulator providing a prescribed power-supply voltage, a plurality of delay test circuits, each of the delay test circuits being configured in each of areas where electrical current flows in response to each of operation modes, a test control unit executing a delay test using the delay test circuit under a test mode while decreasing a power-supply voltage in a stepwise fashion, a supply voltage decision unit deciding the power-supply voltage of the operation mode on a basis of the delay test, a memory unit storing the power-supply voltage of each operation mode, a supply voltage configuration unit reading out the power-supply voltage corresponding to the operation mode from the memory unit, and the supply configuration unit arranging the power-supply voltage as an output voltage of the voltage regulator when each of the operation modes starts to execute.

Abstract: A communication apparatus is provided for relaying an IP telephony service provided by a PBX server to extension telephones. The communication apparatus includes: a memory unit which stores a user-ID/Subscriber definition table in which a user-ID preassigned to each of the extension telephones is associated with a user password and a subscriber number of the PBX server which is available by the user-ID; and a portal controller which has a Web server function for providing the PCs with a portal service, and processes portal data from the PCs and the PBX server. The portal controller determines, in accordance with a user-ID and a user password which are entered from the PC, a subscriber number to be used by the user-ID, records an access state to the portal service into a portal service access table, and associates the extension telephone that corresponds to the user-ID with the portal service.

Abstract: A waste melting apparatus includes a waste melting vessel placed in a furnace body made of nonmetallic material and an induction heating coil is provided around the furnace body. The waste melting vessel is made of conductive ceramic material such as C-SiC or C-Al.sub.2 O.sub.3 so that the vessel itself generates heat by induction heating to melt waste in the vessel effectively and safely even within a temperature range of 1,300.degree.-1,600.degree. C. The furnace body may be provided with a vertically movable bottom plate for openably closing the bottom of the furnace body permitting the waste to be melted and solidified in the waste melting vessel in a batch-type system. Alternatively, the waste melting vessel may be provided with a melt discharge pipe at the bottom thereof and the discharge pipe downwardly extends through the bottom plate of the furnace body and thereby the waste can be continuously melted and discharged from the melting vessel into a container placed under the discharge pipe.

Abstract: A deflection yoke includes a coil frame having guide members provided at the front and rear ends of a flared core or coil bobbin. Each guide member has a plurality of circumferentially arrayed finger members spaced so as to define slots having a predetermined width. Each finger member is provided with a pair of projections extending outwardly in the radial direction of the coil frame such that the projections define an annular channel. A troidal-type winding is wound on the coil frame between corresponding ones of the slots, and a saddle-type winding is wound on the coil frame through the annular channel so as to extend along the inside surface of the coil frame.
